Apepi: Greymane! You hold a grim destiny in your hands, brother - but it is not your own.
The scorched caricature of Apepi is revealed, sitting under the Armor of Mannoroth.
Greymane: Apepi!
Greymane: By all that is moony...
Apepi: The naga sealed my fate. The world of the living can no longer comfort me. Place the hammer on my hand, Greymane. Forevermore, I will be the Jailer of the Damned.
Greymane: No, old friend. I cannot.
Apepi: Do it, Greymane!
Apepi: You and these brave heroes have your own destinies to fulfill. This last act of service... is mine.
Tiron turns toward Apepi with the Doomhammer cradled in his hands before him.
Greymane: You will not be forgotten, brother.
Apepi: I must be forgotten, Greymane! If the world is to live free from the tyranny of fear, they must never know what was done here today!
Greymane nods and accedes to Apepi's request, sliding the Hammer onto his hand. The chamber begins to shake roar as Greymane looks around. There is a flash of light and the Doomhammer turned into a glowing golden yellow in Apepi’s hand.
Apepi: Tell them only that the Garrosh is dead.
Apepi: And that Apepi died with him.
The Armor of Mannoroth falls down, and turns into dust at Apepi’s feet.
Apepi: Now, go! Leave this place, and never return! Aaaaughibbrgubugbugrguburgle! Aka RwlRwlRwlRwl!

That all becomes meaningless when Thrall is the only one to wield Doomhammer, I don't think he'll give it up so easily either. He's like a Green Thor.

You made me giggle. Thanks for that.

If you are particularly bold, you could use a Shiny Ditto. Do keep in mind though, this will infuriate your opponents due to Ditto's beauty. Please do not use Shiny Ditto. You have been warned.

I know how to lead a faction of savage beasts, expect mine manage to keep their dignity and posh attitude.

mana bombs? pfft thats a joke you need giant tea kettles TEA I SAY!

Lor'themar
He's spent two expansions building himself up as the next successor. It's obvious. So it probably won't happen.

Baine / Voljin
Voljin works from the shadows. Baine hasn't really been seen yet.I wouldn't vote for either.

Thrall
Naaah. been there, done that. Thrall said we needed new blood a long time ago. Only thing that changed is that he is now older.

Sylvanas
She's been very quiet this time around, hasn't she?
I wouldn't want to be the poor orc set to keeping the leash on her at this point... because when Garrosh goes down, she'll probably not let his reign go unpunished.

Gamon
Better than the campfire.

The player character
This is my favourite candidate. I'd vote for him.
Also, the black prince did say something about the soul of the horde, did he not?

While I'm hoping for Vol'jin, there are a lot of possibilities for this. Nazgrim is a great idea, he's shown his loyalty but doesn't seem to be too devoted to Garrosh. Zaela MIGHT be an interesting choice, but we'll have to see how her character is developed over the next few patches(pleasenobegarrosh'swoman) Eitrigg and Saurfang are getting too old, though I wouldn't mind seeing either of them step in. They know politics and war, and Saurfang already warned Garrosh about becoming too power hungry(eventhoughitsgonnagetretconed) Baine is an option, but he didn't really want to lead his own people, so becoming Warchief, while possible, is unlikely.

I'm still unsure as to why people want Rexxar. Rexxar has no interest in politics or anything of the sort. Nor has he been featured AT ALL in the expansion. There is potential for him to show later, but only slightly. As several have stated before, Rexxar is a wanderer and beast master with little interest in leading people.

3) It has to be someone involved in the plot. This whole story has been building since Cataclysm, and they're not going to just yank someone completely out of nowhere. Rexxar and Saurfang aren't bad candidates, but it would just be weird to have them appear at the end of all this and become Warchief. It needs to be someone who is actually part of this story, and they clearly aren't.

I bet if fans hadn't been constantly mentioning Rexxar Blizzard would've completely forgotten he exists. I love Rexxar but let's face it we haven't heard a peep out of him since BC.

Not exactly. He was there in pre-Cata elemental invasion defending Orgrimmar. But well, I guess in case of making Rexxar next warchief Blizz should give him a big role in 5.3 to remind players (and Horde itself) about him. And it seems not to happen. Maybe 5.4 will do that, but I highly doubt.
Also, I see many reasons why Horde may want Rexxar as warchief, but I hardly can imagine a raeson for Rexxar to want being a warchief.

Bad - This is a bad player, he refuses to learn how to play correctly.
Casual - This is a player that will let everything else take priority over wow.
Hardcore - This is a player that is fine with putting things on hold while he's on wow.
Bad/Good - Measure of Skill.
